Two Novel Semi-Quantum Secure Direct Communication Protocols in IoT

Yuan Tian, Nanyijia Zhang, Jian Li

As Internet of Things (IoT) technology continues to advance, there is a growing awareness of IoT security within the industry. Quantum communication technology can potentially significantly improve the communication security of IoT devices. Based on semi-quantum cryptography and utilizing single photons, this paper introduces two semi-quantum secure direct communication (SQSDC) protocols for use in smart door locks. Protocol 1 is more efficient, and the efficiency analysis shows that the communication efficiency is as high as 28.57%. Security analysis demonstrates the asymptotic security of the protocols, effectively resisting intercept-measure-resend attacks and entangle-measure attacks from potential eavesdroppers. The extended SQSDC protocol (protocol 2) builds upon protocol 1 by enabling a single qubit to transmit two bits of information, resulting in a double efficiency outcome.

A Review of Semi-Quantum Secure Direct Communication Protocols

Kiran Meena, Narayan Lal Gupta, Vivek Mandot

This review paper includes five distinct protocols in the field of semi-quantum secure direct communication based on different qubit carriers -single photons, EPR pairs, Cluster states, Mediated third party, and two degrees of freedom-polarisation and spatial mode. These protocols have been an- alyzed for their security against several methods of attack like- trojan horse attacks, intercept-resend Attacks, double C-not attacks, and modification attacks. Their efficiency is also estimated and described here. Future work direction in the field of SQSDC is summarised.
